====== Match virtual hard disks (VMware) with their OS disk labels ======

Often disk 1 in your OS isnt disk 1 in your vCenter. But how do you find out which OS disk is the correct disk?

===== Example 1 - Windows Server 2003 =====

Get the OS location via diskmanagement, rightclick on the disk where it says "online" and go to properties, it shows all info you need

Go to your VM into "edit settings", "Location 192" equals SCSI controller 1, "Target Id 4" equals port 4, so look for "Disk xx SCSI(1:4)"

===== Example 2 - Windows Server 2016 =====

Get the OS location via diskmanagement, rightclick on the disk where it says "online" and go to properties, it shows all info you need

Go to your VM into "edit settings", "Location 256" equals SCSI controller 2, "Target Id 6" equals port 6, so look for "Disk xx SCSI(2:6)"

===== Translation VMware SCSI controller <-> Windows Location =====

This table is mostly matching. Sometimes some Locations are somehow skipped 🤷‍♂️

See for yourself in your own environment.
